A requirement for services like stream elements for example to upload their "browser sources" so they can be ran locally from Twitch instead of in a browser which is inefficient and kills performance. Basically a work around to eliminate the need for browser sources. To be clear I'm not saying browser sources should be stopped all together, I'm just saying that if a service has access to Twitch API and has features that use browser sources their should be an option to run those sourced on your channels back end to avoid performance issues and crashes but of course this can only happen if Twitch makes it a contractual requirement that any service using Twitch API must upload these sources so they can be made available on authorized users channel backends...
